Japanese Companies in the US — 2026-10-23
Nippon Steel has announced a massive $3 billion investment to upgrade US Steel’s Mon Valley works in Pennsylvania, marking the largest single project in its $11 billion US commitment. Simultaneously, Japan’s three largest megabanks have decided to skip participation in a third batch of US investment projects, signaling a shift in how Japanese financial institutions approach the $550 billion bilateral investment pact.

Top developments
Nippon Steel
Nippon Steel will invest approximately $3 billion (about ¥470 billion) to install new hot-rolling equipment at US Steel’s Mon Valley works in Pennsylvania, Nikkei and Jiji Press reported on October 22-23. This investment is part of Nippon Steel’s broader $11 billion US investment program running through 2028, which was a key condition of its acquisition of US Steel. The project focuses on upgrading 90-year-old hardware to improve efficiency and product quality, representing the largest single component of the Japanese steelmaker's US expansion.
Mitsubishi UFJ, Mizuho, and Sumitomo Mitsui
Japan’s three largest megabanks—MUFG Bank, Mizuho Bank, and Sumitomo Mitsui Banking—are making final arrangements to forgo participation in a third batch of US investment projects, The Japan Times reported on October 22. While specific reasons were not detailed, the move suggests a cautious approach by major lenders toward specific US investment vehicles within the broader bilateral framework. This decision contrasts with the continued heavy industrial investments by companies like Nippon Steel and the semiconductor sector.

GlobalFoundries (Contextual Update)
While the official announcement occurred earlier in October, local celebrations in New York continued this week regarding the $21 billion investment by Japan to build two chip factories operated by GlobalFoundries. The deal, part of the $550 billion US-Japan trade agreement, involves constructing 300mm wafer fabs in Malta, New York.
Deals, expansion & investment
The primary deal of the past 24 hours is Nippon Steel’s $3 billion commitment to US Steel’s Mon Valley plant. This investment is aimed at modernizing hot-rolling facilities, a critical step in revitalizing the aging infrastructure acquired by Nippon Steel. The scale of this single project highlights the tangible nature of the $11 billion total investment pledge made by Nippon Steel to secure US regulatory approval for its takeover.
Regulation & market context
The decision by Japan’s megabanks to skip the third batch of US investments may reflect growing scrutiny or risk management strategies regarding the implementation of the $550 billion investment pact. Recent reports indicate that while industrial and tech sectors are proceeding with large-scale projects, financial institutions are exercising caution in certain investment tranches. This divergence suggests that the pace of Japanese capital deployment into the US is becoming more selective rather than uniform across all sectors.
On the radar
- Semiconductor Supply Chain: Following the GlobalFoundries announcement, Japanese semiconductor equipment makers are expected to see increased orders, though estimates suggest this represents only 4-8% of their annual sales.
- US Steel Integration: Continued monitoring of how Nippon Steel integrates US Steel’s operations, particularly regarding labor relations and supply chain adjustments in Pennsylvania.
By the numbers
- $3 billion: Investment by Nippon Steel in US Steel’s Mon Valley works in Pennsylvania.
- $11 billion: Total US investment program by Nippon Steel through 2028.
- 3 Megabanks: MUFG, Mizuho, and Sumitomo Mitsui are skipping the third batch of US investment projects.
